I never really liked this ship, which is why I've happily ignored it for months, and successfully have done so until recently. I've seen several fan rumoring how Jelsa "has" to happen in Frozen 2. They even started a FUCKING PETITION to put Jack Frost from Rise of the Guardians in Frozen 2.

I am fine with crossover shipping with Disney and Dreamworks, I even ship Elsa with Hiccup in How to Train Your Dragon. It's true I have many issues with this ship, but I don't care if te ship Jelsa.

But just because a ship becomes popular, does not mean it will happen.
